No one likes to pay property taxes and few have been happy that their tax bills have continued -- for the most part -- to go up as property values have plummeted.

I'll be breaking down the trends behind the larger taxing bodies.

For the Greater Rockford Airport Authority, the blue line represents the Equalized Assessed Value. As you can see the overall county EAV has declined the past four years.

The airport though has been one of the best taxing bodies in terms of its property tax levy (green line). The airport actually lowered its levy four times in the past six years.

By asking for less, the airport's tax extension (purple line) generally has followed the falling property values. The airport this year will collect less in property taxes than it did the year before for the third straight year. In fact, this year the airport will collect less in taxes than it did in 2006.

Although the airport has lowered its levy, it hasn't lowered it as much as property values have fallen so its tax rate has increased. But it hasn't increased nearly as sharply as the vast majority of other taxing bodies.

In 2007, you paid 8.8 cents per $100 dollars of equalized assessed valuation to the airport authority. In 2013, people in the Greater Rockford Airport territory will be paying 10.4 cents per $100 EAV.
